Returns NULL if no execution time has been set yet (e.g. if the command set has not yet been processed).

Methods

ApplyAlgebraOptimisers(ISparqlAlgebra, IEnumerable<IAlgebraOptimiser>)

Apply algebra optimisers to the specified algebra, returning the optimised algebra.

Declaration

public ISparqlAlgebra ApplyAlgebraOptimisers(ISparqlAlgebra algebra, IEnumerable<IAlgebraOptimiser> globalOptimisers = null)

Parameters

Type	Name	Description
ISparqlAlgebra	algebra	The algebra to be optimised.
IEnumerable<IAlgebraOptimiser>	globalOptimisers	Additional optimisers to apply after applying all of the local optimisers specified by AlgebraOptimisers.

Returns

Type	Description
ISparqlAlgebra	The optimised algebra.

Remarks

If the globalOptimisers is null or not specified, the default algebra optimisers defined by Default are applied.
